Common questions and answers about Legal Buyer Certificates
-
Is an electronic certificate legally binding?
Yes, where the parties demonstrate intent and consent; electronic signatures are enforceable under the ESIGN Act (15 U.S.C. §7001) and UETA where adopted. Ensure the four-prong validity test: intent, consent, attribution, and record retention.
-
When is notarization required?
Notarization depends on the effect of the certificate and state law. If the certificate transfers title or is attached to a deed, many states require a notary; check state notary rules for specifics.
-
Who can sign on behalf of an entity?
An authorized officer or person with delegated authority may sign. Consider attaching a corporate resolution or power of attorney to evidence signature authority.
-
Can I use a simple image signature?
Yes, simple electronic signatures are acceptable if attribution and intent are documented. Certain regulated records may require stronger digital signatures or additional authentication.
-
What if the TIN is missing or incorrect?
If the payer does not receive a correct TIN, backup withholding at 24% may be required and IRS reporting penalties can apply; correct errors promptly to avoid withholding.
-
How do I revoke or replace a certificate?
Execute a written revocation or replacement signed by an authorized officer. Maintain both documents with clear timestamps and reason for change to preserve auditability.
